TIMBER-SIZING MACHINE.

T a; allfcchom it may concern:

fBe itknown that L-Hnxnv HANSEN, a citizencf the United States, residingat Olympia ,'(in the county of Thurston and State of \Vashington, haveinvented certain new andiuseful Improvements in Timber- Sizing Machines,of which the following is a specification.

My nvention relates to improvements in timbensizing machines, and. hasfor its principal object totprovide an improved and novel type ofmovable/power operated machine 'for. sizing, channeling and otherwisemilling heavy tlmbersvfor ship construction and the like." PA furtherobject of'my. device is to provide manually operated means for bringingthe cutting tools in 3 contact with the woodg to provide detachableguides for fastening to the timber inorder. to provide a means forretaining the machine in proper relationshipwto the timber; uIn shipconstructi'on and the like, there are many heavy timbers which mustbechanneled, rabbeted,

u chamfered orgotherwise milledby handin order jtoi make :them properlyfit the ship.

This work'isusually' done byshi carpenters by hand toolsand 1s veryexpensive, due to the high cost" of labor.'--x- My machine is designedtoobviajte much' 'of this. hand labor. Other objects willappear as myinvention is more fully explained in the following I specification;illustrated in the accompanying drawing'and :pointed out in the appended: claims.

- flanges-4of' my-machine fit slidably.

In the drawings,Figure"li is a plan view of my device shown in positionon a frag mentof timber, Fig.2 is-a side elevation of same; Fig. 3gis anenlarged detail section of one form of guide shown attached to afragment of timber. v

Referring m orepa-rticularly to the drawings, numeral indicates a.timber along either side-of which aguide 2 is secured by screws,- nailsorthe like. "Guide 2 preferably has a longitudinal channel?) withinwhich My machine has a-- pair of similar sideframes 5 to the lower endbfwhich th flanges i are secured. "-The side members 5 are adjustably heldi'ni parallel spaced relationship to each other bymeans of bolts 6 andfillers 7:2. The side frames 5'are adjustedto properly fitthe timber orto fit the width of the cutting tool which 'itis desired to'use. Theguides in this particular case are shown attached fto the sides of thetimber but it is Specification of Letters Patent;

tor may be attached. of revolving tool, such as a channeler 18,

provided with an upstanding quadrant 8 which has a. slot 9.- A pair ofsimilar hand levers 1-0 are revolubly pivoted to one of the bolts 6 andare provlded with thumb nutsll .which cooperate with the slots 9.Setting screws 12 are also pivoted to levers 10 and pass throughenlarged openings in lugs 13 Patented Apr. 2;, ram.

which are outstanding from quadrants 8.-

The lugs 13 are provided with spherical cups which fita spherical hub 14of a hand wheel? 15. I The hand wheels 15 are threaded on to the screws12 and are used to adjust the le-' vers 10. A shaft'16'is revolublymounted in the lower ends of levers 10 and 1s provided with ashankedconnection 17 to which a flexible shaft from an air or electric momaybe. secured to shaft :16. The operation of my device is as follows:After the guides have been secured'to the timber 1. the machine is.positioned with the flanges 4 in the that the cuttingtool 18 is incontact with the Any desirable'form channels 5 and the hand levers areset so top of the timber; The entire device is-then either shovedforward manually 'or if the tool revolves forwardly, the device will beself propelling and will only need an operator to control its speed andmovement.-

While I have shown a particular form of embodiment of my invention, I amaware that many minor changes thereinwill readily suggest themselvestoothers skilled in the art without departing from the spirit a and scopeof theinvention, andI therefore desire to avoid being limited to theexact form shown and described, w

'Having described my invention, what I claim as new and desire toprotect by Letters Patent,is

' 1. In a device of the class described, the combination of a pair-ofsimilarside frames, adjustable guides within which the said side framesare slidably mounted, levers adjustably pivoted to said side frames, anda power operated tool revolubly mounted on the 1 lower ends of saidlevers.

for "adjusting the position ofthe said side channeled guideswhichcooperate wlth the frames with respect to each other, apair of saidflanges, a

' levers, whereby a pair of similar hand levers pivotally mountedbetween the saidfside frames, a power operated tool shaft, revolublymounted within the ends of Said levers, and means for adjusting theposition of said tool placed upon the .tool be brought into contact witha shaft may the said guides are timber upon which mounted.

3. In a device of the class described, the

combination of a pair of similar side frames having parallel outstandingflanges, means for adjusting the position of the said side frames withrespect to each other, a pair of channeled guides which cooperate withthe said flanges, a pair of similar hand levers pivotally mountedbetween the said side frames, a power operated tool shaft revolublymounted within the ends of said levers, and means for adjusting theposition of said levers, said means including; quadrants integral withthe said side frames, screw rods.

pivotally mounted to each of said levers, spherically faced lugsoutstanding from said quadrants, and spherically hubbed hand threadedcooperation with the said screws. In testimony whereof I afiix mysignature in the presence of two witnesses.
